LM2480

80V Triple Bias Clamp

General Description

The LM2480 driver is an Integrated 80V triple bias clamp

circuit for DC recovery of each of the AC coupled outputs of

a CRT driver. It is well matched with the DAC outputs of the

LM126X family of pre-amplifiers. Each amplifier has its gain

internally set to -18. The IC is packaged in an industry

standard 8 lead molded DIP package.
